After missing the past month with a sprained right thumb, Giants catcher Andrew Susac is back from the 15-day disabled list and will start behind the plate tonight for the start of a three-game series with the Cardinals in St. Louis. Hector Sanchez, who was serving as Buster Posey’s backup, was sent back down to Triple-A Sacramento to clear a spot on the active roster.

As Alex Pavlovic of CSNBayArea.com points out, Posey started 21 out of 26 games behind the plate while Susac was sidelined and got just one start at first base during that time. Posey is getting a day of rest Monday, but he should see some more playing time at first base now that Susac is back to full health. It should help keep him fresh for the stretch run.

Susac, 25, is batting .241/.309/.411 with three home runs and 11 RBI over 123 plate appearances this season.
